Diurnal

Stills from a live-animated installation I've been working for the last few days. Flybys of a mathematical object, a three-dimensional visualisation, built in Processing, of the amount of daylight by day-of-year and latitude. Tomorrow is the equinox: at just 50km from the Arctic Circle, the days are changing length faster now than at any other time of the year, seven minutes a day of extra sunlight.
